OAuth Connections

Generic local OAuth bridge for Agent Zero.

The first provider is Codex/ChatGPT Account:

• signs in with OpenAI's Codex device-code flow
• writes Codex-compatible auth.json credentials
• refreshes local tokens when needed
• exposes a loopback OpenAI-compatible wrapper at /oauth/codex/v1

Tokens in auth.json are password-equivalent credentials. Keep this plugin on trusted local machines only.
